Could not set up Apple Cash

I have restarted my phone, check the region and time zone signed out of iCloud signed back in changed my password used all my other apple products my iPhone 11 my iPad it will not enable my husband sent the rent money like every month and now I’m afraid I won’t be able to get it off because after calling support and escalating it to max they still can’t help. Not even Green dot aka the Apple Cash specialist did anyone ever get their issue resolved ?
